Fixed Wireless Service Coexistence With IMT-A System Within UHF Band

Coexistence analysis is exceedingly important in investigating the possibility for spectrum sharing between IMT-A system and existing wireless services. The 470-862 MHz frequency band is currently allocating to several services such Fixed Wireless Access (FWA). International Telecommunication Union-Radio (ITU-R) sector has allocated sub-bands within 470-862 MHz for IMT-A system. This concurrent operation causes a destructive interference that influences the coexisting feasibility between IMT-A and this existing service, FWA. This paper addresses a timely and topical problem dealing with spectrum sharing and coexistence between an IMT-A systems and FWA service within 790-862 MHz.
